Intended use

The tool is intended for hammer drilling and drilling in

brick, concrete and stone. It is also suitable for drilling

without impact in wood, metal, ceramic and plastic.

Power supply

The tool should be connected only to a power supply of

the same voltage as indicated on the nameplate, and can

only be operated on single-phase AC supply. They are

double-insulated in accordance with European Standard

and can, therefore, also be used from sockets without

earth wire.

Safety hints

For your own safety, please refer to the enclosed safety

instructions.

ADDITIONAL SAFETY RULES

ENB010-1

1. Hold tools by insulated gripping surfaces when

performing an operation where the cutting tool

may contact hidden wiring or its own cord. Con-

tact with a “live” wire will make exposed metal parts

of the tool “live” and shock the operator.

2. Wear ear protertors when using the tool for

extended periods. Prolonged exposure to high

intensity noise can cause hearing loss.

3. Wear a hard hat (safety helmet), safety glasses

and/or face shield. It is also highly recom-

mended that you wear a dust mask, and thickly

padded gloves.

4. Be sure the bit is secured in place before opera-

tion.

5. Under normal operation, the tool is designed to

produce vibration. The screws can come loose

easily, causing a breakdown or accident. Check

tightness of screws carefully before operation.

6. In cold weather or when the tool has not been

used for a long time, let the tool warm up for a

while by operating it under no load. This will

loosen up the lubrication. Without proper warm-

up, hammering operation is difficult.

7. Always be sure you have a firm footing.

Be sure no one is below when using the tool in

high locations.

8. Hold the tool firmly with both hands.

9. Keep hands away from moving parts.

10. Do not leave the tool running. Operate the tool

only when hand-held.

11. Do not point the tool at any one in the area when

operating. The bit could fly out and injure some-

one seriously.

12. Do not touch the bit or parts close to the bit

immediately after operation; they may be

extremely hot and could burn your skin.

SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

Side grip (auxiliary handle) (Fig. 1)

Always use the side grip to ensure operating safety.

Install the side girp so that the teeth on the grip fit in

between the protrusions on the tool barrel. Then tighten

the grip by turning clockwise at the desired position. It

may be swung 360° so as to be secured at any position.
